Devon Energy is buying Grayson Mill Energy's Williston Basin business in a cash-and-stock deal valued at $5 billion as consolidation in the oil and gas sector ramps up.

The transaction includes $3.25 billion in cash and $1.75 billion in stock.

Grayson Mill Energy, based in Houston, is an oil and gas exploration company that received an initial investment from private equity firm EnCap Investments in 2016.

The firm appears to be stepping back from energy sector as it sells off assets. Last month EnCap-backed XCL Resources sold its Uinta Basin oil and gas assets to SM Energy Co. and Northern Oil and Gas in a transaction totaling $2.55 billion. EnCap had another deal in June as well, selling some assets to Matador Resources for nearly $2 billion.

Devon said Monday that the deal significantly expands its position in the Williston Basin with the addition of 307,000 net acres. The basin spans parts of Montana, North Dakota, South Dakota and Canada.

The company anticipates that production from the acquired properties will be maintained at approximately 100,000 barrels of oil equivalent per day next year.

The deal is targeted to close by the end of the third quarter.

Devon said its board will expand its buyback authorization by 67 percent to $5 billion through the middle of 2026. The company also anticipates the deal adding to its dividend payout beginning next year.

Shares of Devon Energy Corp., based in Oklahoma City, fell more than 2.5 percent Monday.

In March, Devon Energy led Houston-based geothermal startup Fervo Energy's $244 million funding round.

Houston renewables developer and Google agree to second solar collaboration

power purchase

EnergyRe, a developer of large-scale renewable energy projects with headquarters in Houston and New York, has signed a renewable energy agreement that will allow Google to invest in and purchase renewable energy credits (RECs) from its projects under development in South Carolina.

Google will be able to pull from energyRe’s portfolio of more than 600 megawatts of new solar and solar storage projects in the state.

The agreement marks the second partnership between the companies. Last year, energyRe and Google signed a 12-year power purchase agreement in which Google would purchase renewable energy from a 435-megawatt solar project. EnergyRe would supply electricity and RECs generated from the solar project to Google to power the equivalent of more than 56,000 homes.

"Strengthening the grid by deploying more reliable and clean energy is crucial for supporting the digital infrastructure that businesses and individuals depend on," Amanda Peterson Corio, head of data center energy at Google, said in a news release. "Our collaboration with energyRe will help power our data centers and the broader economic growth of South Carolina."

EnergyRe's work includes developing high-voltage transmission, onshore and offshore wind, large-scale solar, distributed generation and storage assets in markets around the United States. Its national onshore utility-scale portfolio includes 1,520 megawatts of contracted solar assets and 398 megawatt-hours of contracted battery storage assets.

"This agreement is a milestone in energyRe's mission to develop innovative and impactful clean energy solutions for the future," Miguel Prado, CEO of energyRe, added in the news release."We're honored to partner with Google to help advance their ambitious sustainability and decarbonization objectives while delivering dependable, locally sourced clean energy to meet growing energy demands."

Google aims to achieve net-zero carbon emissions across its operations and value chain by 2030.

Engie partners on major Texas, California battery storage portfolio

power partners

Houston’s Engie North America has partnered with New York-based CBRE Investment Management on a 2.4-gigawatt portfolio of battery storage assets in Texas and California.

The portfolio consists of 31 projects operating in the Electric Reliability Council of Texas (ERCOT) and California Independent System Operator (CAISO) territories. According to a company statement, the transaction represents one of Engie’s largest operating portfolio partnerships in the U.S.

“We are delighted that ENGIE and CBRE IM are partnering in this industry-leading transaction, supporting 2.4 GW of storage that will support the growing demand for power in Texas and California,” Dave Carroll, Chief Renewables Officer and SVP, ENGIE North America, said in the news release.

The deal is also one of the sector’s largest sales completed to date. Engie will retain a controlling share in the portfolio and will continue to operate and manage the assets.

“The scale of this portfolio reflects ENGIE’s commitments to meeting the energy needs of the U.S. and increasing the resilience of the ERCOT and CAISO grids,” Carroll added in the news release. “CBRE IM’s investment reflects their confidence in ENGIE’s proven track record in developing, building, operating and financing renewable assets, both in North America and globally.”

In North America, ENGIE currently has more than 11 gigawatts of renewable production and battery storage in operation or construction. Last year, Engie added 4.2 gigawatts of renewable energy capacity worldwide, bringing the total capacity to 46 gigawatts as of December 31. It also recently made a preliminary deal to supply wind power to a Cipher Mining data center in Texas.

As of March 31, 2025, CBRE IM had $149.1 billion in assets under management and operated in 20 countries.

“We are excited to partner with ENGIE on this high-quality, scaled battery storage portfolio with a strong operating track record,” Robert Shaw, managing director, private infrastructure strategies at CBRE Investment Management, said in the release.

Houston researchers make breakthrough on electricity-generating bacteria

new findings

New research from Rice University that merges biology with electrochemistry has uncovered new findings on how some bacteria generate electricity.

Led by Caroline Ajo-Franklin, a Rice professor of biosciences and the director of the Rice Synthetic Biology Institute, the team published its findings in the journal Cell in April. The report showed how some bacteria use compounds called naphthoquinones, rather than oxygen, to transfer electrons to external surfaces in a process known as extracellular respiration. In other words, the bacteria are exhale electricity as they breathe.

This process has been observed by scientists for years, but the Rice team's deeper understanding of its mechanism is a major breakthrough, with implications for the clean energy and industrial biotechnology sectors, according to the university.

“Our research not only solves a long-standing scientific mystery, but it also points to a new and potentially widespread survival strategy in nature,” Ajo-Franklin, said in a news release.

The Rice team worked with the University of California, San Diego's Palsson lab to simulate bacterial growth using advanced computer modeling. The simulations modeled oxygen-deprived environments that were rich in conductive surfaces, and found that bacteria could sustain themselves without oxygen. Next, they confirmed that the bacteria continued to grow and generate electricity when placed on conductive materials.

The team reports that the findings "lay the groundwork for future technologies that harness the unique capabilities" of these bacteria with "far-reaching practical implications." The team says the findings could lead to significant improvements in wastewater treatment and biomanufacturing. They could also allow for better bioelectronic sensors in oxygen-deprived environments, including deep-sea vents, the human gut and in deep space.

“Our work lays the foundation for harnessing carbon dioxide through renewable electricity, where bacteria function similarly to plants with sunlight in photosynthesis,” Ajo-Franklin added in the release. “It opens the door to building smarter, more sustainable technologies with biology at the core.”
